Mandarin is my native language, but I came to the US when I was 10 years old. Twenty years later, even though I'm still fluent in Mandarin, I have to admit my English is better mainly because I live in an English-speaking environment.

Spanish is my second language, though I have not used it in a very long time.Although I tried to learn Japanese way back before I ever took a Spanish class, but that doesn't count because I never really got skilled at Japanese, at all.The language that will probably, in the future, be my second most skilled language is Mandarin, but we'll see how that goes.

Languages, from most fluent to more recent: English, Spanish, French, Japanese, Mandarin.
